Please note that the shareholder funding of gateways is different from other models since we do not reward the provision per se (there is only an operator management fee) and we use the Nu owned funds (NuOwned liquidity operation).
Besides, I suppose (please correct me if I wrong) that you assume that all shareholder funded liquidity is then broadcast in the QT client as either T1 T2 or T3 .
I believe that we want to have the best liquidity broadcast into the client with a spread lower or equal to 1%.
Perhaps we can make sure that liquidity offered at spread higher than 1% does not get broadcast but nonetheless can be found on the order books. In that case we could create another Tier. Right now, it seems that it is called T1.2 as defined here.
Right now, I believe the client does not broadcast T1.2 as it only considers liquidity whose spread is lower than 1%.
Please correct me if I am wrong.
